&nbspREMARK: The diatom taxonomic coordinator and Karin studied NAWQA populations and determined that it is better to have everything under A. rivulare, although the names that are being changed are valid and might be used in the future for proper specimens. Although the name A. rivulare is well defined, in NAWQA it is a compisite taxon in which several things have been lumped. Because it is clear to us that A. rivulare is dominant among all these lumped taxa, it makes more sense to use the later name.
